Abstract: 920,389. Self-propelled missiles. GENERAL ELECTRIC CO. May 8, 1961, No. 16612/61. Class 9 (2). [Also in Group XXVI] In a re-ignitable solid fuelled rocket motor in which the propellant and nozzle are arranged to give a chamber pressure below that at which combustion is achieved, means are provided to direct additional mass flow into the chamber to increase the pressure therein to a level at which combustion of the solid fuel is sustained. A fuel 14-nozzle 17 arrangement 11, Fig. 2, as above has coupled to it by way of valve 20 and pipe 19, a liquid monopropellant source 18 (e.g. hydrogen peroxide with catalyst screen 21) which provides the additional mass flow required for main fuel burning pressure in the chamber 12. As shown in Fig. 5, a series of solid fuel chambers 30, 28 may be provided, each controlling solid fuel chamber pressures adjacently downstream, the series being initiated by liquid flow addition to chamber 30 (as in Fig. 2). It is stated that by such an arrangement control can be achieved where liquid mass flow is only 0.1% of the solid mass flow. In a further embodiment, a solid fuel booster charge in the main chamber is initiated by the liquid mass flow in order to achieve a combustion pressure in the main chamber. Regenerative heating of the liquid mass flow may be used as indicated by 22 (Fig. 4, not shown). The control fluid may be a reactive fluid such as fluorine, chlorine tri-fluoride, nitric acid, sulphuric acid, nitrogen tetra-oxide, liquid sodium, or phosphorus depending on the solid propellant used.

Title: Laundry apparatus
IPC: D06F34/08
Filed: 1969-03-31
Abstract: 1,261,361. Laundry apparatus. PHILCOFORD CORP. 31 March, 1969 [12 April, 1968], No. 16814/69. Heading F4G. A laundry apparatus has an enclosure, through which air is passed to dry fabrics therein, means capable of heating the air sequentially at a higher and a lower rate and control means for sensing the dryness of the fabrics at the beginning of the period of lower heating and operable to either terminate drying or continue the period of lower heating rate according to the dryness of the fabrics. In a domestic washing machine (10), the fabrics are washed conventionally in a perforated basket 14 mounted on a stub shaft 15 inside a tub 23. During the drying cycle, the basket is rotated and air, heated by resistance heater 24 and driven by blower 27, passes through the duct 25 and is directed into the basket 14 through loading opening 13. After passing through the basket the air is drawn off through the perforations in the basket, is cooled and dehumidified and then returned to the blower 27 through duct 29. The air is cooled and dehumidified in a condenser 26 by passing over cold water trickling down the inner surface of the tub 23 from a supply conduit controlled by valve 28. The drying cycle is selected by push buttons (36a) and a master timer switch (35) mounted on the front panel (11) (Figs. 1, 3, not shown). The first stage in the drying of permanently pressed clothes involves heating the drying air by the resistance heater which is supplied from a 240 volt source, giving 4400 W., at the end of this part of the cycle, the thermostat 33 mounted on the bearing plate 22 of the tub 23, senses the temperature of the exhaust air from the basket 14, and therefore indirectly senses the dryness of the fabric. If the fabric is dry the timer automatically allows the apparatus to cool down and sounds a warning signal. If the fabric is still damp the heater 24 is automatically supplied from a 120 volt source giving 1100 W., and the fabric is dried further until the thermostat 33 reaches the correct temperature when the cooling down cycle is initiated.
